Rows of cobbles designed to knobble the unwary cyclist seem to be springing up all over the place. On Providence Place, just by St Barts church, our council has laid these cobbles. What are they for? They clearly don't calm cars, but are a hazard to cyclists using this as a quiet route from Preston Circus to the North Laine. Ironically, because of the road camber, the middle section where the cars go is relatively lower! They are also to be found on Ann Street.
